I just want to deliver express, but you insist on recruiting me?

Chapter 75 Who taught you to omit it like this?

"Commander, you saw the plane, it's just like that."

“It’s raining so hard.”

"Let's go back."

Lin Xiao turned back and pouted: "Back?"

What a joke.

You let me go back after taking off my pants.

The silly and cute plane in front of him whetted his appetite.

If it was a regular appearance, it would be fine.

Lin Xiao had seen many planes before, so he didn't have to get to the bottom of it.

But now.

There is something in front of me that breaks the conventional cognition. How can I go back now?

"I've been a soldier all my life, so this little rain is nothing." Lin Xiao waved his hand.

Chen Chen: "I have something to do. I'm not feeling well. How about I go back?"

Lin Xiao smiled heartily and grabbed Chen Chen's wrist directly: "Minister Zhang, you are responsible for holding an umbrella for Mr. Chen today. If you get wet, you will be punished by military law."

Zhang Taihuan followed suit with a smile: "I promise to complete the task."

"Come on, tell me about this plane."

Chen Chen looked back at Wei Xiao helplessly.

At this moment, she was already lying on the stool, covering her cold heart with an expressionless face.

Chen Chen could only sigh and introduce in a low voice: "SFNB01, the name was inspired by our gratitude to Shunfeng."

"As a startup company, Chendun is fortunate to have received support from the wind."

"We are grateful to the whole company and hope that Shunfeng Group will get better and better in the future..."

Lin Xiao patted Chen Chen's back and said, "Talk to President Wei about these in private. He said they are useful. Where is the machine data?"

He had experienced Chen Chen's mouth before.

Most people can’t stand it.

This is why Lin Xiao came in person.

If Zhang Taihuan or Sun Changxing were put in charge, Chen Chen might be able to confuse them.

"Row……"

"Wingspan 15.4."

"Captain 7.5."

Hearing this number, Sun Changxing nodded secretly.

The length of the aircraft is half the wingspan.

No wonder it looks so out of place.

The wingspan to fuselage ratio of a normal aircraft is usually 1:1.
There are also cases of 0.7 or 0.8, but they are not mainstream.

"Wearing leather pants over cotton pants, there must be a reason. What's your starting point for making the plane so cute?"

"In Qianjiang." Chen Chen said naturally.

Lin Xiao pinched Chen Chen's shoulder fiercely: "Speak properly."

"hiss……"

"SFNB01 is similar to the two-tailed scorpion, and its main function is still to deliver packages."

"We have summarized the shortcomings of the twin-tailed scorpion. The fuselage is too long and its flexibility is affected."

“At this size, a truck can easily load it and it can be transported on a standard four-lane highway.”

Sun Changxing didn't buy it at all: "Bullshit, you already have airplanes, why are you still considering road transportation?"

Seeing that he couldn't fool her, Chen Chen could only tell the truth: "You are also in the aviation industry. Do I need to tell you the benefits of a large wingspan?"

"To account for lift characteristics?"

"Look, you already know the answer, and you're still asking me?"

Theoretically speaking, the longer the wing is, the closer it is to a 2D flow field, and the higher the lift-to-drag ratio.

Specifically on aircraft performance.

There will be significant gains in both ceiling and endurance.

Most aircraft designed for high-altitude, long-range flight, such as the U-2, M55, and the solar-powered global aircraft in recent years, have wingspans that are much longer than their fuselages.

"So what is the maximum ceiling of SFNB01?" Sun Changxing was very curious.

"More than 7000 meters."

Hear this number.

Lin Xiao suddenly frowned.

He remembered the relevant data of the double-tailed scorpion clearly: its ceiling was 10,000 meters.

SFNB01 is much inferior.

Sun Changxing was also a little skeptical: "The lift-to-drag ratio of your aircraft should be good."

"Why are you getting lower and lower?"

"It shouldn't be."

Chen Chen helplessly spread his hands: "I've already said that, it's a private enterprise, the technology is not sophisticated, the double-tailed scorpion is an accident."

"What about the range? With such a long wingspan, the mileage and flight time must have been a big breakthrough, right?"

"More than 1200 kilometers." Chen Chen said simply.

As soon as this number comes out.

Everyone was obviously disappointed.

The ceiling is inferior to that of the Scorpion.

The flight time is also unsatisfactory.

This data level is already very good compared to other manufacturers.

But it is far from enough for Morning Shield.

At this point, people like Zheng Yucun who were new to the Morning Shield began to have doubts. It was too risky for them to develop a completely different aircraft instead of extending the Twin-Tailed Scorpion.

Whether the appearance is good or not, it all serves the performance.

The performance numbers are significantly reduced, and the appearance of this car is just ugly.

But at this time, Zhang Mingrui stepped out from the crowd and looked at Chen Chen suspiciously.

"I just had a chat with the confidentiality department."

Chen Chen's heart tightened.

Zhang Mingrui's mouth turned more and more crooked: "According to the information they have, SFNB01 has conducted a small-scale test flight before, right?"

Chen Chen's eyelids twitched: "Right...right?"

"People say that you flew at least 10,000 meters on your first test flight."

"Yeah……?"

"And they said you did a test flight at 40 a.m. the day before, and the plane landed in the early morning of the third day. The flight time was almost 1200 hours, and you told me that the maximum range was only ?"

"I don't remember clearly..."

Chen Chen felt bitter and frivolous.

I thought to myself, this is not a confidentiality department, it's purely a leak department.

Only at this moment did Lin Xiao understand.

The Scorpion has a flight time of 34 hours, and the SFNB01 has a flight time of 40 hours.

Moreover, SFNB01 is smaller in size, so even if its power level and aerodynamic layout are worse, its mileage cannot be less than half, right?

"You kid, have you learned to lie with your eyes wide open?"

Lin Xiao pretended to be angry.

But Chen Chen's attitude was firm: "I am absolutely not lying."

"Bullshit, people say your test flight ceiling is over 10,000."

"Yes, I'm over 7000 meters. Didn't you hear the word 'more'?"

Chen Chen was very confident and said that Lin Xiao suddenly couldn't do anything.

"How much...how much is left?"

Chen Chen: "The remaining 7000."

"Fourteen thousand???"

Chen Chen nodded, and everyone present was stunned.

Did you say that?

A multiple left?

My brain circuit is almost going to my gallbladder.

The person who designed you must be a genius.

Lin Xiao immediately asked: "What's the mileage?"

"More than 1200."

"How much more!?"

"1500 more."

"Two thousand seven!?"

Chen Chen: "Simple addition, don't doubt yourself, it's two thousand seven."

"..."

The rest is just an integer multiple.

Now there are 1500 more.

Who taught you to round off like that?

The person who designed you must be a pervert.

Lin Xiao finally understood that he couldn't trust a single punctuation mark from Chen Chen's mouth.

If you're not careful you could end up in a ditch.

Sun Changxing and Zhang Mingrui looked relieved.

There is no other reason.

When the lift-to-drag ratio of SFNB01 is high, such data is what it should be.

Then their eyes turned back to admiration when they looked at Chen Chen.

A high lift-to-drag ratio and a long wingspan certainly have advantages.

But it also tests the strength of the fuselage.

Otherwise, all airplanes can have long arms and short bodies, which is nothing special.

This shows that Chen Chen's aircraft has core technology.

Sun Changxing analyzed: "In this case, the requirements for materials are raised in disguise."

Zhang Mingrui: "Yes, strengthening the fuselage means reducing the payload, and the extra weight of the wings must be used to compensate for it."

Lin Xiao listened to the two's analysis and immediately turned to ask Chen Chen: "What about the payload quality?"

Chen Chen was a little confused. After hesitating for two seconds, he said, "Just over 900 kilograms."

"How much has it passed!" Lin Xiao had already learned nothing, and asked before the other party finished speaking.

"One ton."

"1.9 tons? Speak properly!"

Lin Xiao was so angry that his mouth was crooked. Was this math taught by your physical education teacher?
The others on the side were half laughing, half marveling at the sight, and shouting in their hearts how awesome it was.

Chen Chen hugged his arms and started to move.

I didn't lie either.

1.9 tons＞900 kg.

Over 900 kilograms, if you don’t accept it, bite me.
